Select the incorrect statement

Options

A. Museums often have collections of skeletons
B. Separate taxonomic keys are required for each taxonomic category
C. Taxonomic keys are based on the contrasting characters
D. Monograph is useful in providing information for identifications of names of species found in an area

Answer

To solve the question of selecting the incorrect statement, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the First Statement
**Statement:** Museums often have collections of skeletons.
**Analysis:** This statement is true. Museums are known to house various collections, including skeletons, for educational and research purposes.

### Step 2: Analyze the Second Statement
**Statement:** Separate taxonomic keys are required for each taxonomic category.
**Analysis:** This statement is also true. Taxonomic keys are specific tools used for identifying organisms, and different taxonomic categories (like species, genus, family) often require different keys for accurate identification.

### Step 3: Analyze the Third Statement
**Statement:** Taxonomic keys are based on contrasting characters.
**Analysis:** This statement is true as well. Taxonomic keys utilize contrasting characteristics (called couplets) to help in the identification process of organisms.

### Step 4: Analyze the Fourth Statement
**Statement:** A monograph is useful in providing information for the identification of the name of species found in an area.
**Analysis:** This statement is incorrect. A monograph typically provides detailed information about a particular taxon (like a family, genus, or species) rather than a comprehensive identification of all species found in an area.

### Conclusion
Based on the analysis, the incorrect statement is the last one: "A monograph is useful in providing information for the identification of the name of species found in an area."
